this.api.elements doesn't work in page object sections

[Eriusik]

Describe the bug

It doesn't work after upgrade from 1.24 to 1.3.2. TypeError: Error while running "elements" command: Function.prototype.apply was called on a.btn-download, which is a string and not a function

Page Object

TestPage.js

```js module.exports = { sections: { buttons: { selector: '#index-container .download .download', elements: { downloadButton: 'a.btn-download' }, commands: [{ checkInstall: function() { this.api.elements('css selector', this.elements.downloadButton.selector, function(result) { console.log(result); }); return this; } }] } }, } ```

Test

sampleTest.js

```js const test = { tags: ['1browser'], '@disabled': false, before: function (browser) { }, 'Test open nightwatch': function(browser) { const testSection = browser.page.TestPage().section.buttons; browser.url('https://nightwatchjs.org/'); testSection.checkInstall(); }, after: function (browser) { browser.end(); } }; module.exports = test; ```

Run with command

$ nightwatch test/sampleTest.js --your-other-arguments-here
